LAND-ROLLER.

Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed June 16, 1906. Serial No. 822,087.

To all whom it may concern.-

Be it known that I, GEORGE J. CARPENTER, a citizen of the United States,residing at Bronson, in the county of Branch and State of Michigan, haveinvented a new and useful Land-Roller, of which the following is a specification.

This invention has relation to land-rollers and it consists in the novelconstruction and arrangement of parts as hereinafter shown anddescribed.

The object of the invention is to provide a land-roller of substantialconstruction which may be easily turned to change its course ordirection in traveling over the ground.

It consists, primarily, of parallel bars spaced apart and resting upon apair of alined rollers, said rollers being in vertical alinement underthe forward bar. A horizontal frame is superimposed upon said parallelbars and is provided with a forwardly-extending portion the central axisof which is substantially midway between the inner ends of the saidalined rollers. A rectangular frame is pivoted at its middle at thecentral longitudinal axis of said forwardly-extending portion of thesuperimposed frame. The roller is journalcd in suitable bcarings carriedby said rectangular frame. The rectangular frame is locatedsubstantially in advance of the said parallel bars that it may describeat least three-quarters of a turn without coming in contact or forcingits attachments in contact with the said bars. J ournal-bearing supportsof suitable construction are provided and will be described hereinafter.

In the accompanying drawings, forming a part of this specification,Figure 1 is a top plan view of the roller. Fig. 2 is a verticallongitudinal sectional view of the same, and Fig. 3 is a perspectiveview of the roller-bearing support.

The roller consists of the parallel bars 1 1 and rollers 2 2, which arein alinement with each other and located vertically under the forwardbar 1. The journal-bearing supports 3 depend from the forward bar 1 andwill be described hereinafter. The bearings 4 are carried bythe supports3 and receive the ends of the shaft 5 that passes longitudinally throughthe center of the roller 2. The braces 6 extend from the rear edges ofthe supports 3 to the rear bar 1. The frame 7 is superimposed upon thebars 1 1 and is attached to the same. Said frame is provided With theforwardly-extendmg portion 8, the

center axis of which is substantially midway between the inner ends ofthe rollers 2 2. The rectangular frame 9 is pivoted at its middle at thecentral axis of the forward portion S'of the said frame 7. The saidframe 9 is provided with the cruciform-braces 10 at the point ofintersection of which the king or pivot bolt 11 is located. The roller 2similar to that heretofore described is attached in a suitable manner tothe frame 9 and supports the same. The said frame 9 is provided with thehooks 12, which are adapted to receive and retain eyes carried by thecross-piece at the end of the tongue 13.

It is understood that the draft-animals (not shown) are attached to thesaid tongue.

The bearing-supports 3 are made from sheet metal. As they are ofsubstantially the same construction a description of one will answer forall. The support consists of the vertical back wall 1 1, at the edges ofwhich are located the parallel flanges 15 15, which extend in planes atright angles to the back wall 14. The upper ends of said flanges 1.5terminate in the lugs 16, which are bolted or otherwise secured to theparticular portion of the frame of the roller to which thebearingsupport is applied. The upper end 17 of the back wall 14 of thesupport is bent in at right angles to the said back wall between theflanges 15 15 and is also adapted to be secured to the under side of theparticular portion of the frame of the roller to which the said supportis applied. The bearing 4 is supported by the bolt 18, which passesthrough the side flanges 15 15 and also through the said bearing. Itwill thus be seen that the bearing-support is provided with specialconstruction which although being constructed of sheet metal is soformed as to brace itself in all directions against the strains found inimplements of this character. Also the bearings 4 may be easily andreadily removed from the supports for repairs or substitution. It willalso be observed that the square frame 9,-if detached from the tongue13, may describe a complete revolution without interfering with the rearrollers 2 2 or other attaclnnents. However, when the tongue 13 isattached to the said frame 9 by reason of said attachment the frame 9may describe but three-quarters of the rotation. The sweep of such anarc is all that is necessary in an implement of this kind to permit thesame to turn freely and in short distances.

As shown in Fig. 3 of the drawings, the lugs 16 are not bent down atright angles to the flanges 15, but continue in the same vertical planeswith the said flanges. the left shows-the method in which thebearing-supports are applied to the frame when the lugs 16 are in thesame vertical planes as the flanges 15.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is I A land-roller consisting of a frame, a series oflongitudinally-alined rollers supporting the rear end thereof, a framepivotally attached to the forward end thereof, and a roller supportingthe last said frame, said frame-supports comprising metallic sheets aFig. 2 at i per ends of the back walls and extending behaving backwalls, side flanges formed at the edges thereof and extending in planesat right angles thereto, bearings located between said flanges, flangesformed at the uptween the side flanges and attaching means securing thelast said flanges to the frame of the roller, the upper ends of saidside flanges terminating in lugs which are also attached to the frame ofthe roller.

In testimony that I clailn the foregoing as my own I have heretoafl'lxed my signature in the presence of two witnesses. v

GEORGE J. CARPENTER.
